Abstract
A tool configured to cut a workpiece includes a tool head which has a receiving contour in which the workpiece is received, and a movable cutting edge with a cutting contour. In the course of a cutting process, the cutting edge passes through the receiving contour. The cutting edge is subjected to the effect of an advancement part and can be moved to such an extent in the cutting direction(s) that it can pass all the way through the workpiece. In an embodiment, a position of the cutting edge reached after the cutting edge has passed all the way through the workpiece, the cutting edge, with removal from the advancement part, can be moved out from the cutting direction(s).
Claims36
A tool for cutting a workpiece, comprising:
- first and second guide parts and a base holding part, the first guide part defining a first channel and the second guide part defining a second channel;
- a holding part defining a workpiece receiving contour configured to receive the workpiece, the holding part having a first channel on a first side of the workpiece receiving contour and a second channel on a second opposite side of the workpiece receiving contour, the holding part being pivotally coupled to the first guide part such that the holding part is positionable in a first position relative to the guide parts in which the first channels are aligned, the second channels are aligned and a workspace is formed into which each of the first channels and each of the second channels opens, and a second pivoted position relative to the guide parts in which the first channels are not aligned and the second channels are not aligned;
- a movable cutting edge defining a cutting contour, wherein the cutting contour is configured to be received within the first and second channels of the guide parts and the first and second channels of the holding part and is further configured to pass by the workpiece receiving contour during a process of cutting the workpiece in a cutting direction;
- and
- a piston movably mounted between the guide parts, the cutting edge being engaged with the piston, wherein the cutting edge to moves along the first and second channels of the guide parts and thereafter moves along the first and second channels of the holding part upon movement of the piston relative to the guide parts when the holding part is positioned in the first position, and wherein the cutting edge is pivoted relative to the piston by pivoting the holding part into the second pivoted position when the cutting edge is seated within the channels of the holding part and the cutting contour is moved past the workpiece receiving contour of the holding part.
A tool for cutting a workpiece, comprising:
- a holding part and first and second guide parts, the holding part and the first and second guide parts defining a workpiece receiving contour configured to receive the workpiece, a first channel on a first side of the workpiece receiving contour and a second channel on a second opposite side of the workpiece receiving contour, wherein each channel has an open end;
- a movable cutting edge having a first side edge positioned within the first channel and an opposite second side edge positioned within the second channel, the cutting edge defining a cutting contour between the first and second side edges, wherein the first and second side edges of the cutting contour are configured to slide along the respective first and second channels, the cutting contour is configured to pass by the workpiece receiving contour and is configured to pass through the open ends of the first and second channels during a cutting process of cutting the workpiece in a cutting direction;
- and
- a plate configured to move the cutting edge relative to the first and second channels, wherein the cutting edge is pivotably connected to the plate, and wherein the cutting edge is pivotable relative to the plate once the cutting edge passes through the open ends of the first and second channels and moves past the workpiece receiving contour.
